Nanoscale magnetic structures enables many interesting science as the structure dimensions become comparable to characteristic length scales, which has immediate application in magnetic data storage, magnetic memory and spintronics devices. Moreover, the order between nanostructures as in patterned arrays, becomes crucial as the mesoscopic effects produced by the confinement and proximity can be controlled and modified by their geometrical configuration. Ordered arrays of nanostructures are particularly interesting to study, as one can probe both the individual and collective behavior of the elements. The most important properties that of interest to study is at nanoscale where change can happen in smaller time scales (e.g. fluctuation of magnetic domain wall, ultrafast demagnetization), so the challenge is to understand science of ultra-small structures at ultra-fast time scales. We are using laboratory based experimental techniques as well as large scale facility (neutron and synchrotron radiation based techniques) to characterize/observe the nano-scale properties.
